Description
7902929-4 verksam även under körning och att fordonet inte såsom vid användning av differentialspärr varje gång först måste stanna för mekanisk in- läggning av spärren. I förbindelse med en làsningsreglerad fordons- bromsanläggning är kostnaden för byggdelar vid den uppfinningsenliga startreglerkopplingen särskilt låg enär man i stor utsträckning kan använda byggdelarna till antilåsanläggningen. 7902929-4 is also effective while driving and that the vehicle does not, as when using a differential lock, have to stop every time for mechanical loading of the lock. In connection with a lock-controlled vehicle brake system, the cost of components in the starting control coupling according to the invention is particularly low, since the components can be used to a large extent for the anti-lock system.
Vidare fördelaktiga utbildningar av uppfinningen är angivna i de osjälvständiga kraven.Further advantageous teachings of the invention are set forth in the dependent claims.
Uppfinningen förklaras närmare nedan med hjälp av bilagd rit- ning över ett utföringsexempel. Ritningen visar sehematiskt en anord- ning (startreglerkoppling) 1 för att hindra slirning av ett drivet hjul i en tvakretsbromsanläggning med två tryckbehållare 2 och 4, en bromsventil 6 och med fyra hjul samordnade magnetreglerventiler 8, 10, 12, 14 i en antilåsningsreglerad fordonsbromsanläggning (endast delvis visad) samt bromscylindrar 16, 18, 20, 22 och tryckmedelsled- ningar 24 för bakhjulsbromskretsen och 26 för framhjulsbromskretsen. _ Anordningen har en elektrisk kopplingsanordning 28 för fast- ställande av varvtalsskillnader mellan de drivna hjulen och de icke drivna hjulen samt för alstring av styrsignaler för inmatning av tryck i det slirande drivhjulets bromseylinder. Kopplingsanordningen 28 kopplas in av föraren över en brytare 30 när han konstaterar hjul- slirning varvid samtidigt magnetreglerventilerna 8 och 10 aktiveras att stänga och en magnetventil 32 aktiveras vilken över en grenventil 33 släpper fram tryekmedel till de drivna hjulens magnetreglerventi- ler 8 och 10. Som brytare används en automatiskt urkopplande tryck- knappsbrytare för att hindra oavsiktlig inkoppling.The invention is explained in more detail below with the aid of the accompanying drawing of an exemplary embodiment. The drawing seematically shows a device (starting control coupling) 1 for preventing slippage of a driven wheel in a two-circuit brake system with two pressure vessels 2 and 4, a brake valve 6 and four-wheel coordinated solenoid control valves 8, 10, 12, 14 in an anti-lock controlled vehicle brake system ( only partially shown) as well as brake cylinders 16, 18, 20, 22 and pressure medium lines 24 for the rear-wheel brake circuit and 26 for the front-wheel brake circuit. The device has an electrical coupling device 28 for determining speed differences between the driven wheels and the non-driven wheels and for generating control signals for inputting pressure into the brake cylinder of the sliding drive wheel. The coupling device 28 is switched on by the driver over a switch 30 when he detects wheel slip, at the same time the solenoid control valves 8 and 10 are activated to close and a solenoid valve 32 is activated which via a branch valve 33 releases pressure means to the solenoid control valves 8 and 10 of the driven wheels. switch uses an automatically disengaging pushbutton switch to prevent accidental connection.
Konstateras i kopplingsanordningen 28 en hastighetsskillnad som är högre än ett förutbestämt tröskelvärde alstras en reglersignal som avmagnetiserar den med det otillåtligt snabbt roterande hjulet samordnade magnetventilen och åstadkommer en tryckinmatning över den- na magnetreglerventil i hjulets bromscylinder. Tryekinmatningen pågår så länge tills hastighetsskillnaden åter ligger under tröskelvärdet varvid företrädesvis en stegvis tryckhöjning tillämpas.If a speed difference which is higher than a predetermined threshold value is detected in the coupling device 28, a control signal is generated which demagnetizes the solenoid valve coordinated with the impermissibly fast rotating wheel and provides a pressure input over this solenoid control valve in the wheel brake cylinder. The pressure input continues until the speed difference is again below the threshold value, whereby preferably a stepwise pressure increase is applied.
Bromstrycksregleringen kan även ske så att trycket kontinuer- ligt eller i pulser höjas så länge tills det icke slirande praktiskt taget stillastående hjulet överskrider en förutbestämd hastighet och att då det uppnådda trycket hálles konstant. Så snart en förutbestämd hastighetsskillnad underskrides sänkas åter trycket vid det bromsade hjulet stegvis. Överskrides då åter hastighetsskillnaden höjas broms-The brake pressure regulation can also take place so that the pressure is continuously or in pulses increased until the non-slip practically stationary wheel exceeds a predetermined speed and that then the pressure reached is kept constant. As soon as a predetermined speed difference is exceeded, the pressure at the braked wheel is gradually reduced again. If the speed difference is exceeded again, the braking
